Application June 2 3,

1 Claim.

This invention relates to a conveyer designed primarily for handlingmilk cans.

Under the laws of most states it is necessary for the milk producer toplace the cans containing the milk in coolers. As the filled cans arequite heavy, it is a diificult matter generally to place them in andremove them from the coolers which, ordinarily, are in the form oftroughs containing cold water.

An object of the present invention is to provide a simpleand efiicientmeans whereby the cans can be readily raised and lowered relative to thetrough and moved toward and from positions therein and thereover withoutrequiring the strength and skill heretofore necessary.

With the foregoing and other objects in View which will appear as thedescription proceeds, the invention consists of certain novel details ofconstruction and combinations of parts hereinafter more fully describedand pointed out in the claim, it being understood that changes may bemade in the construction and arrangement of parts without departing fromthe spirit of the invention as claimed.

In the accompanying drawings the preferred forms of the invention havebeen shown.

In said drawings- Figure 1 is an elevation of the ccnveyer, the coolerand base portion being shown in section.

Figure 2 is a section on line 2--2 Figure 1.

Figure 3 is a section on line 33, Figure 1.

Figure 4 is a section on line 44, Figure 1.

Figure 5 is a section on line 5-5, Figure 1.

Figure 6 is an elevation of a portion of a slightly modified form of thedevice.

Referring to the figures by characters of reference I designates a postwhich, in the'structures shown in Figures 1 to 5 inclusive, is mountedat its lower end on a thrust-bearing 2 while its upper end portion ismounted in a fixedly held bearing 3.

Secured to the post I at. a suitable elevation is an arm 4 of anydesired length and reenforced' preferably by means of a brace 5connecting the arm to a collar 5 secured to the post. This arm carries apulley I near its free end and another pulley 8 near the post.

A bracket 9 made up of spaced plates or wings 5 I0 is secured to thelower portion of the post I as shown at I! and the wings to of thisbracket are formed with opposed arcuate slots I2 in which a cross-pin I3is mounted to slide. This pin extends through a lever I4 which issupported between the wings I!) and has an exten- 1937, Serial No.149,971

sion handle I5 whereby it can be actuated readily. Lever I4 carries apulley I6.

Extending between and carried by the wings I0 and adjacent to the post Iis a stop pin I? located in the path of the lower portion of lever I4when said lever is shifted out of normal position.

A clamp I8 is secured to the post I above but adjacent to the bracket 9and secured to this clamp is one end of a cable I9 the other end ofwhich carries a grapple 20 made up of opposed arms pivotally connectedat 2| and provided with hooks 22 turned inwardly toward each other.

Cable I9 extends from clamp I8 through lever I l and partly aroundpulley I6. From this pulley it extends upwardly over pulleys 8 and I andthence downwardly to the grapple.

When the lever I4 is in its elevated or raised position as is shown inFigures 1 and 2, the

I grapple 20 is in its lowermost position where it can readily be placedin engagement with the ears or handles H of a milk can C. The conveyorconstituting the invention is adapted to be located adjacent to a coolerwhich can be in the form of a trough T containing cold water. If

a can is to be placed in the cooler the arm 4 is swung into position soas to support the grapple 20 directly over the can whereupon the hooks22 can be placed in engagement with the handle H. The upwardly extendinglever I I is then swung downwardly. This will cause the lower endportion thereof to move against stop pin I'i while pin I3 will traveldownwardly within the slots I2. At the same time pulley I6 will drawupon the cable I9, causing the grapple 29 to move upwardly and carry thecan with it. While the can is elevated the post I can be turned so as toswing arm 4 to position where the can will be suspended over the cooler,this swinging action being effected by pulling or thrusting on theextension I5 of lever I4 while it is lowered. After the can has beenbrought to proper position, the lever is allowed to swing upwardly andthis will pay out the cable I9 and allow the grapple 20 and the can tomove downwardly into the cooler to the position shown in Figure 1. Thisoperation can be repeated for removing the can from the cooler.

By mounting the lever as described and by connecting it in the mannershown to the cable I9, the leverage effected through the actuation oflever I4 is greatly increased so that the heavy can can be raised andlowered with the expenditure of very little effort.

Instead of mounting the post I so that it will turn as described, saidpost can be fixedly mounted and, as shown in Figure 6, a sleeve 23 supspaced wings having arcuate slots, a stop connecting the wings, a levermovably mounted between tlie wings, a member carried by the lever andmovable within the slots during the actuation of the lever, said leverbeing movable against the stop to be fulcrumed thereon during saidactuation, a lifting cable, a can engaging means at one end thereof,means for attaching the other end of the cable to the post, a pulleycarried by the lever for holding the cable thereto, and 10 spaced cablesupporting pulleys on the arm.
